What is the answer if you have 70 degrees and 30 degrees in a triangle but you need to find out how much the other angle is?

The inner angles of a triangle add up to 180 degrees. 180 - (70 + 30) = 80 degrees.

How do you find the third angle of a scalene triangle?
If you have the other two angles, you can subract them from 180 degrees, which is the sum of the angles in any triangle.
How do you find a missing dimension for a right angle triangle?
In a right triangle, all the angle measurements together add up to be 180 degrees. And since it is a right triangle, one of the three angles is 90 degrees so if you are given one of the angles other than the right angle's measurements, you can find the angle measurements. Here's an example: There is a right triangle. One angle measures to be 45 degrees. What is the missing angle measure? Well we know that one angle must be 90 degrees and the other (as we were told) is 45 degrees. 90+45=135 and we know that a right triangle=180 degrees total and 180-135= 45. The missing angle is equal to 45 degrees! hope this makes sense and it helped.
What is the first step when trying to find a missing angle?
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
A base angle of an isosceles triangle is 6 degrees more than the vertex angle. Find the vertex angle?
56 degrees
If three sides of triangle are 8cm 6cm 10cm Then find largest angle?
It is a right angle triangle and its largest angle is 90 degrees
What is the measure of the third angle of a triangle if one angle measures 15 degrees and the other measures 85 degrees?
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.

How do you find the measure of angle?
The sum of the angles of a triangle equal 180 degrees. The sum of the angles of a quadrilateral equal 360 degrees. To find the measure of an angle for a triangle, you must first be given the other two angle numbers, unless it is an equilateral triangle, in which all angles would equal 60 degrees. To find the measure of a quadrilateral, you must first be given the other three angle numbers, unless it is a square, in which all angles would equal 90 degrees.
